How does it work?

Optional Flow Switch / Sensor is designed to detect Flow / No Flow. A rare earth magnet is located within the red PVDF float of the new F-300 flowmeters. When the magnet passes through the Alarm Trigger Zone of the Sensor Accessory, the built-in contact closure switch sends a signal to external devices.Note: Two alarms can be placed onto one meter to obtain both ‘Flow Switch’ and ‘Flow Sensor’ capabilities. See diagrams below.

Capabilites

Flow Rate Sensor

Detects if water flow rate is at desired level. A built-in contact closure switch can remotely turn on/off a chemical pump and/or other external devices when flow rate is within desired range. Additionally, this can be used as an alarm signal if flow rate is not within flow range target, potentially indicating a clogged filter, malfunctioning equipment, closed valve, etc.

With flow rate sensor installed at targeted flow rate, the sensor can detect if your flow is within desired range. The alarm window is approx. 10GPM (varies).

ie. Target water flow rate is 65 GPM, alarm is placed so that 65 GPM is positioned in middle of indicator window. Sensor will trigger alarm at flow from 60 to 70 GPM

Flow Switch

Detects if water is flowing through the pipe. If float leaves “Alarm trigger zone,” a built-in contact closure switch can remotely turn on/off a chemical pump and/or other external devices.

With sensor installed at the base of the scale, the switch can detect a flow / no flow situation.

Installation of the New F-300

Blue-White Engineer Patrick Murphy reviews the benefits of choosing the F-300 for closed system flow monitoring. Not only does the F-300 install in just minutes, new improvements to the meter allows for tight space installation, a float that remains steady, improved accuracy (+/-5%), and a float that does not stick.
